x^2-4y^2\x^2+4xy+4y^2除以(x^2-2xy)结果是不是 1\x(x+2y)呐?
x^2-4y^2\x^2+4xy+4y^2除以(x^2-2xy)
结果是不是 1\x(x+2y)呐?
x^2-4y^2\x^2+4xy+4y^2除以(x^2-2xy)结果是不是 1\x(x+2y)呐?
是(x^2-4y^2)/(x^2+4xy+4y^2)除以(x^2-2xy)吗?
如果是的话:
[(x²-4y²)/(x²+4xy+4y²)]÷(x²-2xy)
=[(x²-(2y)²]/[x(x+2y)²(x-2y)]
=(x+2y)(x-2y)/[x(x+2y)²(x-2y)]
=1/[x(x+2y)]
1/(x²+2xy)
补充答案:
楼主给出的解是正确的.
祝贺楼主!
因式分解:12xy^2(y-x)+xy^3(x-y)+4x^2y(x-y)
(x+y)(x+y+2xy)+(xy+1)(xy-1)(x+y)(x-y)+4(y-1)
计算:2xy/(x+y)².(x+y)/4y
(x^-4y^)/(x^+2xy+y^)/(x+2y)/(2x^+2xy)
因式分解 x-xy+3y-3x 2x+xy-y-4x+5y-6
2x(x-y)+4xy(y-x) 因式分解2x(x-y)+4xy(y-x) 因式分解
(x^2+2xy+y^2-4xy)*(x^2-2xy+y^2+4xy)
已知x*x-4xy+4y*y=0 求[2x(x+y)-y(x+y)]/(4x*x-4xy+y*y)的值?
化简:3x^2-[5xy-(x^y-3xy)+4x^2y-8xy]
因式分解x^2(x-y)-4xy(x-y)-4y^2(y-x)
计算:4xy-(x+y)^2/xy(x+y)(x-y)÷x^2+xy-2y^2/x^2y+2xy^2
化简2(x²y+xy)-3(x²y-xy)-4x²y
(-3x^y+2xy)-( )=4x^+xy
因式分解2x(x-y)^4 - x²(x-y)² + xy(y-x)²RT
x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x²
(-x-2y)(x²-2xy+4y²)
-2x³y+4x²y-2xy
计算:[(x-y)^2-(x+y)^2]/(-4xy)=
